Garmin Training Center 3.6.0.5 Beta

Here is the change list for this version:
GTC no longer uses legacy "bin files" as its data storage format, and is now using a more reliable open-source embedded database. Note: GTC no longer stores its application data in the "All Users Program Data Path", but is now in the current user's app data path
"C:\Users\<WindowsLogin>\AppData\Roaming\GARMIN\Tra iningCenter\UserData" in Windows Vista/7
GTC has been re-engineered to scale better for larger user data sets.
GTC provides the ability to convert existing legacy user bin file accounts. A user can automatically migrate old users to new user accounts on a 1-1 basis or merge multiple legacy accounts into a single new user file. This feature was designed to be robust so that it will attempt to recover any valid legacy data even from "corrupted bin files" that were not accessible from GTC 3.5.3 and earlier.
GTC now supports Power workout creation/editing
GTC now supports Repeat Step targets other than step count in support of newer devices that provide this feature(Repeat Until).
GTC now supports Power Zones and Bikes in the User Profile
GTC now supports auto-error reporting like more current Garmin Windows applications
GTC can now properly sync user profile with FIT mass storage devices such as the Edge 500/800 & Forerunner 110/210.
GTC no longer has a rigid folder structure where top level folders force a sport type on the folder's sub-elements. User's can create sub-folders and mix elements in any manner they desire regardless of the sport type of the activity or workout. The only provided "System Folders" are "My <User Data Type>" and "Imported <User Data Type>" where <User Data Type> is Activities, Workouts, or Courses, and a folder with the default "Example Workouts".
GTC will allow the user to directly import Activity Fit Files from the Import->History menu.
GTC provides the user with the ability to change the sport type on activities and workouts since this can no longer be accomplished by moving an activity between Sport specific folders.
While GTC will not bring in multiple copies of the same activity to "My Activities" when doing a receive from device, the application also no longer requires that activities have a unique start time. Thus, a user may have an activity that was imported from a TCX file in "Imported Activities" that duplicates an activity brought over from the device in "My Activities".
